3 Hard Surface Installation Procedures Homogeneous Inlaid Roll widths PRODUCT CONSTRUCTION ROLL WIDTH Maximum MVER BioSpec MD Homogeneous Inlaid 6 wide rolls only 3 lbs 75% RH with M-Guard V-88 8 lbs 90%RH Because Mannington Commercial Resilient Sheet Flooring products are intended for use in high-traffic areas, underfloor selection and preparation are especially important. In most cases, remove all existing floor coverings before installing these commercial products. (You must strictly follow all federal, state, and local regulations regarding the removal of existing flooring.) Furthermore, all concrete under floors must be tested for moisture before starting the installation. Mannington requires that the concrete be tested for moisture using either the anhydrous calcium chloride test following ASTM F 1869 procedures and or the in-situ relative humidity test following ASTM F Maximum permissible MVER are determined by product construction and adhesive type (see chart above). NOTE: While either of these industry accepted moisture testing methods may be used, the results are not exchangeable, if both tests are performed they must both be in the acceptable range to be considered valid. Handling procedures It is imperative to maintain the material, adhesive, and job site at a minimum temperature of 65 F and a maximum temperature of 85 F for 48 hours before, during, and after the installation. If the material has been stored at colder temperatures, it will need to be unrolled and allowed to relax overnight before proceeding with the installation. When using V-95 adhesive, make sure to maintain the adhesive, floor covering, and job site at a minimum temperature of 65 F for a minimum of 48 hours before, during, and after the installation. NOTE: If the flooring contractor elects to install new floor covering over an existing floor covering, the flooring contractor assumes all responsibility as to the suitability and continued performance of the existing floor covering. If removal of existing resilient floor covering is required, follow all recommended Resilient Covering Flooring Institute (RFCI) work practices at Please be aware that installing these products over existing flooring may reduce their excellent indentation resistance. These products may also be installed over properly prepared and approved wood panel or wood composition panel underlayments on wood subfloor systems. WARNING: Do not sand, dry sweep, dry scrape, drill, saw, beadblast, or mechanically chip or pulverize existing resilient flooring, backing, lining felt, paint, asphaltic cutback adhesives, or other adhesives. These products may contain asbestos fibers or crystalline silica. Avoid creating dust. Inhalation of such dust is a cancer and respiratory tract hazard. Smoking by individuals exposed to asbestos fibers greatly increases the risk of serious bodily harm. Unless positively certain that the product is a non-asbestos-containing material, you must presume it contains asbestos. Regulations may require that the material be tested to determine asbestos content. The Resilient Floor Covering Institute (RFCI) document Recommended Work Practices for Removal of Resilient Floor Coverings should be consulted for a defined set of instructions addressed to the task of removing all resilient floor covering structures. For more information visit the Resilient Floor Covering Institute at Patching & leveling compounds We recommend the use of latex/portland cement trowelable underlayments or self-leveling cementitious products for repairing or leveling concrete subfloors. Sand and fill approved underlayment panel joints using a latex/portland cement compound. The properties and handling characteristics of Mannington MVP 2023 Fast Patch make it an ideal compound for use under Mannington Commercial resilient sheet flooring products. Do not use gypsum or mineral-based patching compounds in commercial applications under any circumstances. 1

4 Cutting & fitting Mannington Commercial inlaid products are flexible and will handle easily when cutting and fitting. This product characteristic enables the installer to fit the material using freehand knifing techniques. If the job site is complex and requires a precise fit, use pattern-scribing techniques. The material may also be fit using direct scribing techniques. Once the material has been fit, it is necessary to tube or lap back half of the sheet to expose the underfloor for adhesive application. Take care when folding the material back. Always fold the material in a wide radius to avoid sharp kinks and creases, which may cause breaks in the product. Applying adhesive Fully adhere Mannington Commercial resilient sheet flooring to an approved underfloor. After you have trimmed the material to fit the room, tube or lap it back to expose the underfloor. Apply adhesive with the following recommended notched trowels. Spread adhesive over 100% of the exposed subfloor, leaving no gaps or puddles. Maintain uniform coverage by keeping the trowel clean and properly notched. In most cases it is advisable to give the adhesive sufficient open time. Open time allows the moisture to flash off the adhesive, permitting the adhesive to develop more body and immediate tack. Open time is always determined by subfloor porosity and atmospheric conditions. Be certain to provide ample open time on non-porous subfloors and at seam lines. After the adhesive has begun to tack-up, roll the sheet forward into the adhesive to avoid trapping air. Do not drop or flop the material into the adhesive. Roll the floor covering with a three-section, 100 lb (or heavier) floor roller in both directions. After the first half of the sheet has been adhered and rolled, fold back the second half and repeat the procedure. CAUTIONS: When providing open time, do not permit the adhesive to skin over or dry. Too much open time will result in insufficient bonding. BioSpec MD and LifeLines II should be installed using V-82 adhesive over porous substrates. Use V-88 or V-95 adhesive over non-porous substrates. Mannington V-95 adhesive has low initial tack. It may be necessary to apply weights to the floor covering, especially in the seam area, until the adhesive sets. When using V-95 adhesive, roll the adhered flooring with a 100 lb (or heavier) roller within one hour after the flooring is installed. Wait one to two hours and re-roll the flooring again to ensure full contact has been achieved. Re-rolling the material will also help remove any trapped air bubbles. Seam cutting and seam sealing PRODUCT BioSpec MD METHOD TO USE Recess Scribing method Recess scribing seams for inlaid construction BioSpec MD When seaming is required with BioSpec MD, position the materials as Reverse Sheets. Cut the selvage edge of one sheet using a straightedge and a utility knife or edge trimmer. Trim off about 3/8 from the edge. Trimming is necessary since 6 rolls are typically stored on-end causing compression on one edge. Or the rolls might even be damaged during transport. Position the sheets in such a manner that the top sheet will overlap the previously straightedged sheet by approximately 1/2. Fold back the sheets to expose the underfloor and apply the appropriate adhesive. Place the trimmed sheet into the adhesive while providing sufficient overlap of the second sheet; then lay in the second sheet. Roll the adhered areas to within 6 of the seam line with a 100 lb three-section floor roller. Adjust the recess scriber before actually cutting the seam by cutting a slit in a scrap piece of resilient flooring material. Insert the button on one edge of the slit. The needle should just touch the opposite side of the slit. Make sure to set the scriber to produce a net fit, neither gapped nor too full. Using a recess-scribing tool, insert the scriber against the straightedge piece of resilient. Use the bottom end of the tool, the guide, to follow the bottom sheet and lightly score the top sheet with the needle of the scribing tool. Keep the scribing tool perpendicular to the seam when scribing. 2

5 Cut the seam net with a utility knife (straight or hook blade). Cut the seam by following the scribed mark. A burr may be created on the seam in the needle of the scriber is set too deep or too much pressure is applied. CAUTION: If the scriber is pulled too tightly against the bottom sheet, the seam will be too full to have the potential to peak. After scribing and cutting the seam, roll the seam area with a hand seam roller to bring the seam edges level. Re-roll the entire adhered area with the 100 lb floor roller. Thoroughly clean the seam area and wipe dry. Recommended seaming methods-chemical or heat welded seams PRODUCT CHEMICALLY WELDED HEAT WELDED Biospec Md Recommended Recommended-preferred method Chemical seam sealing BioSpec MD Thoroughly clean the seam of all adhesives, dirt, etc, before sealing it. If the seams are to be chemically welded, use Mannington Commercial MCS 42 Seam Sealer. When inserting the applicator tip into the seam cut, it is crucial that the seam sealer be applied to the full depth of the cut. Wipe off all sealer from the surface of the seam with a clean white cloth dampened with mineral spirits. Because the seam sealer should not be allowed to remain on the surface of the flooring more than 30 or 40 seconds, it is recommended 5 or 6 lineal feet of seam be sealed and then wiped clean. Be certain to overlap each application of seam sealer. Heat welding Heat welding is the act of fusing resilient sheets together with a heated thermal vinyl weld rod. This technique is suitable for installing the following Mannington Commercial resilient sheet flooring products: BioSpec MD. NOTE: Heat welding is the preferred method of sealing seams for homogeneous products. Weld rods Mannington s weld rod is available on spools and is designed to fit the most popular heat welding guns. Mannington offers a broad range of solid rod colors to coordinate with all of our heat-weldable flooring. Camouflage weld rods are offered for BioSpec MD. Heat welding recommendations To achieve good sealing results, knowledge of proper heat welding procedures is important. A repeated stop/start method will produce rough uneven seams, creating an unpleasant appearance. Temperature setting is critical to the success of any heat welding application. If the welding gun is set too hot or applied too slowly, the flooring is likely to burn, char, or craze the surface next to the weld rod. If welding gun is not hot enough or applied too quickly, the weld may have poor fusion. Follow all Mannington temperature requirements to achieve an even seam with good bond strength and integrity. After waiting 24 hours for the adhesive to dry, use a power-grooving machine to cut a groove the entire length of the seam. Adjust the machine so the depth of the groove is about two thirds of the product s thickness. Stop machine grooving several inches away from the wall. Extend the groove to the wall using a hand-grooving tool. Prior to heat welding, allow the flooring adhesive to completely dry. Preheat welding gun and determine proper temperature setting and router depth by practicing on scrap pieces of flooring. Make certain the speed nozzle is clean and free of obstructions. Insert welding rod into the speed nozzle allowing approximately 3 to extend out. Arrange welding rod in such a manner that it will not interfere with the application. Be careful when inserting the welding rod because the nozzle is extremely hot. Pull the gun along the length of the seam toward your body while maintaining a downward pressure. Keep the gun perpendicular to the floor. Weld the seam at a constant, even speed. Stop and change direction of the weld when you are near the back wall. Pull the gun out of the groove and cut the weld rod. Remove the urethane coating before heat welding inside corner by grooving or sanding. Performed metal corner caps may also be used. 3

6 Allow welded rod to cool, and then groove the installed rod with a hand-grooving tool. Grooving the rod makes it possible to achieve complete seam coverage when you start seaming from the opposite direction to finish the job. Reposition yourself and your tools at the back wall and continue welding into the grooved rod you just made so there are no missed spots in the seam. It is important to achieve a smooth, continuous coverage of the rod into the seam. After the welded rod shrinks and cools for approximately 30 minutes, trim down the excess by using the following two steps: Remove approximately two thirds of the exposed welded rod. Use a spatula trim knife and trim plate to trim off the top layer. There should be about 1/32 excess weld rod projected above the surface of the resilient. The second step is to trim the welded rod level until it is flush with the surface of the resilient sheet. Use an extremely sharp spatula knife without the trim place at a 5º to 10º angle to the floor surface. Keep the sharpened side down against the welded rod. Be careful not to cut or dig into the resilient surface. Inspect the finished seam carefully and remove any missed high spots with a spatula knife. If there are low spots, the seam weld may require a rod reapplication. Once the entire area has been trimmed and inspected, smooth out seam with one of the two recommended methods. When using camouflage weld rods, both steps are required. 1. Glaze Curing the Seam: Apply heat from the welding tool by removing speed nozzle and using the same heat setting to direct a flow of heat from the gun along the length of the seam. 2. Seam Sealing the Seam: To smooth out the seam, apply MCS 42 seam sealer to the welded seam and leave it on no longer than 30 to 40 seconds. Wipe all sealer from the surface of the seam with a clean white cloth dampened with mineral spirits. Do not wipe the seams of camouflage weld rods. Allow the sealer to be absorbed into the rod. Both of these two last steps reduce porosity of the trimmed rod and glaze the surface of the welded rod to produce a smooth, continuous appearance. Coat the trimmed weld rod with the Quantum Guard HP marker to protect the rod from soil. Finishing & maintenance Protect all exposed edges of floor covering with trim or restrictive moldings. Remove all scraps and trash from the jobsite. Remove all adhesive smears or residue from the surface of the floor covering with a clean cloth dampened with mineral spirits. After 24 hours of the completed installation, thoroughly clean the floor. Mannington Commercial resilient sheet flooring should receive three to five coats of a high-quality, cross-linked, acrylic floor finish before the flooring is put in service. Mannington Commercial sheet products with the Quantum Guard HP wear layer does not require polish. Refer to delayed maintenance procedures. CAUTION: Do not wash the floor until 48 hours after installation. After 48 hours, you may damp mop the floor to remove any residual surface dirt. Repairs Replacing damaged areas If possible, the floor covering repair piece should come from the original installation. Typically, consumers retain leftover pieces from the original installation. Tape the repair piece over the damaged area and double-cut using a steel square as a guide. Remove the damaged area and scrape the subfloor clean. Apply adhesive on the back of the repair piece and insert into the flooring. Roll the repair piece with a hand seam roller. Use the appropriate Mannington seam sealer to seal all cuts. Flash coving resilient sheet products All Mannington resilient sheet goods can be installed using the flash coving method. This edging technique, often preferred by hospitals and other health care facilities, is a process of extending the resilient flooring up the wall to create a wall base. Normally, the floor covering is extended up the wall to a height of 4 to 6. As with all resilient installations, proper preparation of the work area is critical to the success of the installation. Clean the underfloor carefully and make certain it is structurally sound. 4

7 The juncture of the floor and wall also needs special preparation before beginning a coved installation. Follow the instructions below to install the cove cap and the cove stick (cove fillet strip). Measure desired height for the cove caps at each corner and strike a chalk line. Attach aluminum or vinyl cove caps at this height using flathead nails with a hammer or brad pusher, or use contact cement. Always miter inside and outside corners in the cap. When mitering the outside corners, file the ends of the cap smooth. Use a specially designed miter tool with interchangeable die sets to make corners on the cove cap. This tool eliminates sharp edges at the outside corners. Cove sticks support the resilient flooring as it is flashed up the wall, eliminating the chance of puncturing the resilient flooring. Firmly secure plastic or wood cove sticks where the floor meets the wall with adhesive or nails. Use nonstaining nails and set the flush with the stick. The stick should have a minimum radius of 1 1/8 and be precisely mitered at all inside and outside corners. Provide a smooth transition in the door casings and other areas where the coving ends by cutting back to the cove stick. Tack the scribing felt to the wall with brad type nails before beginning to scribe it. Use a combination square, a small metal ruler, or a 1 piece of resilient to pattern scribe the felt. Fit the scribing tool up inside the cove cap and scribe the felt by sliding the tool along the cap as you mark the felt with a pencil. Scribe and cut the outside corners of the felt using a utility knife and the inside corners of the felt, using dividers. After scribing the entire work area, position the pattern squarely on the resilient sheet flooring and transcribe the pattern with pencil dividers. Be careful when cutting the material on the inside and outside corners. Dry fit the material. Inside corners should fit snug, but not be forced into position. Make sure to always position the shorter side first and then the longer side. Gently pull material away from the wall. Apply the appropriate adhesive to the floor, wall, cove cap, and cove stick. Allow the appropriate amount of open time. Fit the material back into place. Remember to always position the shorter side first. Roll the flooring with the appropriate size roller (use a hand roller on coved areas). Apply the appropriate seam sealer at all seams, following the recommended directions for the resilient floor being installed. The most demanding aspect of a coved installation is forming the outside corners. Fill outside corners with a boot type plug, rather than a V-type plug, on the least visible wall. The plugged corner fill piece should extend back at least several inches from the corner. The seam of the floor should be below the cove stick. Using an underscriber, scribe the back of the plug at the corner. This will mark the pattern of the corner on the plug. Cut along the scribed line at a 45 angle with a curved trim knife or a utility blade while holding the plug steady with a metal ruler and your other hand. When cutting, leave the face of the plug longer than the back. Check the fill piece for accurate fit. Make any minor adjustments to the plug as necessary to fill the space correctly. Remove the fitted fill piece and apply the appropriate adhesive. Reposition the fill piece and apply seam sealer. NOTE: If planning to heat weld the seams, be aware that only Mannington Commercial BioSpec MD products can be used. Remove the urethane coating before heat welding each inside corner by grooving or sanding. Preformed metal corner caps may also be used. 5

8 Heterogeneous General information All recommendations are based on the most recent available information. These installation specifications are for fully adhered installations of Mannington Commercial heterogeneous products, Primus and Vivendi. 1. Cut order pieces should be rolled face out on a core to take to the job site. Otherwise, the roll will flatten or oval, making it difficult to get the floor covering to lay flat when unrolled. 2. The floor covering, adhesive, and room temperature must be kept at a minimum temperature of 65 F with a maximum of 90ºF for at least 48 hours before and during, and 48 hours after installation. 3. All subfloor patching on and below grade must be done with a non-shrinking, water-resistant Portland cement patching compound such as Mannington MVP Never install Mannington sheet goods over residual asphalt-type (cut back) adhesive. It can bleed through the new floor covering. Residual asphalt-type adhesive must be removed or isolated from the finished flooring by providing a mechanical barrier, such as Mannington MVP Must be fully adhered using Mannington V-82 or M Guard V-88 on porous or non-porous substrates. Use Mannington Commercial high performance V-95 two-part epoxy adhesives on non-porous substrates or in areas that require high performance adhesives (i.e. under hospital beds, exceptional high traffic areas). 6. All seams must be sealed by either using Mannington Commercial MLG-33 chemical seam sealer or heat welded with Mannington solid color weld rod. Subfloor information Careful and correct preparation of the subfloor is a major part of a satisfactory sheet floor covering installation. Roughness or unevenness of the subfloor will telegraph through the new floor covering, resulting in an unsightly surface and excessive wear on high spots. Proper subfloor selection and preparation are essential for a trouble-free job. wood subfloors 1. GENERAL When installing Primus or Vivendi sheet flooring products over wood panel underlayments, Mannington Commercial M-Guard V-88 adhesive (or equivalent) must be used. All wood floors must be suspended at least 18 above the ground. Adequate cross-ventilation must be provided and the ground surface of a crawl space must be covered with a suitable vapor barrier. Wood subfloors directly on concrete or installed over sleeper construction are not satisfactory for the installation of Mannington Resilient flooring products. Wood subfloors must be covered with a minimum ¼ or heavier underlayment rated panel to assure a successful finished flooring installation. 2. UNDERLAYMENT Many times wood panel subfloors are damaged during the construction process or are not of underlayment grade. These panels must be covered with an approved underlayment. Underlayment panels are intended to be used to provide a smooth surface on which to adhere the finished floor covering. It must be understood that underlayment panels cannot correct structural deficiencies. Particleboard, chipboard, construction grade plywood, any hardboard and flakeboard are not recommended as underlayment. All have inadequate uniformity, poor dimensional stability, and variable surface porosity. Mannington Resilient Floors will not accept responsibility for adhered installation over these subfloors. In all cases, the underlayment manufacturer or underlayment installer is responsible for all underlayment warranties. 3. UNDERLAYMENT REQUIREMENTS Panels intended to be used as underlayment should be specifically designed for this purpose. These panels should have a minimum thickness of ¼. Any panels selected as an underlayment must meet the following criteria: Be dimensionally stable. Have a smooth, fully sanded face so the graining or texturing will not show through. Be resistant to both static and impact indentation. Be free of any surface components that may cause staining such as plastic fillers, marking inks, sealers, etc. Be of uniform density, porosity and thickness. Have a written warranty for suitability and performance from the panel manufacturer or have a history of proven performance. Any unevenness at joints between panels must be sanded to a level surface. Gaps between panels, hammer indentations, and all other surface irregularities must be patched with Mannington MVP 2023 underlayment or equivalent. 6

9 concrete subfloors 1. Concrete subfloors must be dry, smooth, and free from dust, solvent, paint, marker, wax, grease, oil, asphalt sealing compounds and other extraneous materials. The surface must be hard and dense, and free from powder or flaking. 2. New concrete slabs must be thoroughly dry (at least six weeks) and completely cured. Curing agents, surface hardeners and other additives may cause adhesive bonding failure. These should be removed by sanding or grinding. 3. All concrete slabs must be checked for moisture before installing material. Follow ASTM F-1869 recommendations for performing calcium chloride test. Alternate Test F-2170 with a relative humidity level of 75% maximum. 4. Mannington Commercial heterogeneous flooring products must never be installed where hydrostatic pressure or excessive moisture vapor emissions may exist. Moisture emission from subfloor cannot exceed 3 lbs. per 1,000 sq. ft. per 24 hours. Mannington will not assume responsibility for floor covering failure due to hydrostatic pressure or moisture vapor emission that exceed the levels stated above. When using Mannington Commercial M-Guard V-88 the moisture level of concrete must be no greater than 8 lbs. /1000 sq. ft. /24 hours (2.27 kg /92.9 m2 /24 hours) as determined by a calcium chloride test according to ASTM F-1869 test method and/or 90% RH as determined by ASTM F in situ relative humidity test. If both tests are performed the RH test is the qualifying standard. The ph must be below The final responsibility for determining if the concrete is dry enough for installation of the flooring lies with the floor covering installer. 6. Concrete floors with a radiant heating system are satisfactory, provided the temperature of the floor does not exceed 90 F at any point. 7. Holes, grooves, and other depressions must be filled with Mannington MVP 2023 patching and leveling compound (or equivalent) and troweled smooth and feathered even with the surrounding surface. Installation Existing resilient floor coverings To achieve maximum product performance, Realities, Primus and Vivendi should not be installed over existing resilient floor coverings. In the rare cases where removal of the existing resilient floor covering is not an option, the existing flooring must be covered with Mannington MVP-2023 or other appropriate porous underlayment. NOTE: If the flooring contractor elects to install new floor covering over an existing floor covering, the flooring contractor assumes all responsibility as to the suitability and continued performance of the existing floor covering. If removal of existing resilient floor covering is required, follow all recommended Resilient Covering Flooring Institute (RFCI) work practices at NOTE: Consult Mannington s Commercial Installation Guide or the Recommended Work Practices brochure from the Resilient Floor Covering Institute for specific instructions on removal of old resilient floor covering. Visit WARNING: Do not sand, dry sweep, dry scrape, drill, saw, beadblast, or mechanically chip or pulverize existing resilient flooring, backing, lining felt, paint, asphaltic cutback adhesives, or other adhesives. These products may contain asbestos fibers or crystalline silica. Avoid creating dust. Inhalation of such dust is a cancer and respiratory tract hazard. Smoking by individuals exposed to asbestos fibers greatly increases the risk of serious bodily harm. Unless positively certain that the product is a non-asbestos-containing material, you must presume it contains asbestos. Regulations may require that the material be tested to determine asbestos content. The Resilient Floor Covering Institute (RFCI) document Recommended Work Practices for Removal of Resilient Floor Coverings should be consulted for a defined set of instructions addressed to the task of removing all resilient floor covering structures. For more information, visit the Resilient Floor Covering Institute at Cutting and fitting It is imperative that the material, adhesive and job site be maintained at a minimum temperature of 65ºF or a maximum of 90ºF 48 hours before, during and 48 hours after installation. If the material has been stored at colder temperatures, it will be necessary to unroll the material and allow it to relax over night before proceeding with the installation. If the job site is complex and requires a precise fit, traditional pattern scribing techniques should be used. The material may also be fit using direct scribing techniques. Once the material has been fit, it will be necessary to tube or lap half of the sheet back to expose the underfloor for adhesive application. Care should be taken when folding the material back. Always fold the material in a wide radius to avoid sharp kinks and creases, which may cause breaks in the product. 7

10 Adhesive application After the material has been trimmed to fit the room, it should be tubed or lapped back to expose the underfloor. On porous substrates, V-82 adhesive should be applied with a 1/16 wide, 1/32 deep spaced 1/32 apart notched trowel. M-Guard V-88 can be used on both porous and non-porous substrates. Over porous substrates apply with 1/16 x 1/32 x 1/32 U notched trowel. (1.6mm x 0.8mm x 0.8mm). Over non-porous substrates use a 1/16 x 1/32 x 5/64 U notched trowel(1.6mm x 0.8mm x 2mm). V-95 two-component epoxy adhesive must be used on all non-porous substrates and in areas demanding high performance. Follow all directions on adhesive container. V-95 has low initial tack, it may be necessary to apply weights, particularly in the seam area, until adhesive sets. V-95 should be applied with a 1/16 wide, 1/32 deep, spaced 1/32 apart notched trowel and then rolled with a 3/8 nap paint roller. The adhesive must be spread over 100% of the exposed subfloor, leaving no gaps or puddles. Uniform coverage can be maintained by keeping the trowel clean and properly notched. After the adhesive has been applied, roll the sheet forward into the adhesive to eliminate trapping air. Do not drop or flop the material into the adhesive. Roll the floor covering with a three-section 100 lb. or heavier floor roller in both directions. After the first half of the sheet has been adhered and rolled, fold back the second half and repeat the procedure. When using V-95, the flooring should be rolled with a 100 lb. floor roller within one hour after the flooring is installed. Wait 1 2 hours then re-roll again to insure full contact and to remove any trapped air. CAUTION: When providing open time, do not permit the adhesive to skin over or dry. Too much open time will result in insufficient bonding. Seaming Primus and Vivendi are available in 6, 9 and 12 widths. Choose product width to eliminate unnecessary seams and minimize waste. When seaming is required with Mannington Commercial heterogeneous sheet flooring, the materials should be positioned Reverse Sheets for seaming. The construction of heterogeneous flooring requires that the seams be cut using the trace cutting technique. The selvage edge of one sheet should be straight-edged approximately 3/8 from the edge. Position the sheets in such a manner that the straight-edged top sheet will overlap the untrimmed bottom sheet and maintain the pattern match. Carefully trace along the edge of the top sheet with a utility knife with a sharp blade or a cutting tool designed for this purpose. Remove the trimmed selvage edge of the bottom sheet. Once the seams are cut, weigh the sheets and tube or lap back the sheets to expose the underfloor. Apply the appropriate Mannington adhesive using the correctly notched trowel over 100% of the exposed underfloor. After providing sufficient open time for the adhesive, lay the straight-edged sheet into the adhesive first and then lay in the second sheet. Roll the adhered areas to within about 6 of the seam line with a 100 lb. three-section floor roller. Roll the seam area with a hand seam roller to bring the seam edges level. Re-roll the entire adhered area with the 100 lb. floor roller. Thoroughly clean the seam area and wipe dry. Heat welding heterogeneous flooring Seams may be heat welded using coordinating solid color weld rod. Wait at least 24 hours after initial installation to allow the adhesive to cure before grooving the flooring product to receive the heat weld rod. Proper temperature of the heat welding tool is critical to the success of this process. Heat welding is always dependent on speed of application and temperature. Practice on a scrap piece of material to determine optimum speed and temperature. After the weld rod has cooled, trim the applied weld rod in two steps. Always use a trim plate with a sharp spatula trim knife for the first pass. Trim weld rod flush with the spatula knife, being careful to not gouge the vinyl surface. Coat the trimmed weld rod with the Quantum Guard HP marker to protect the rod from soil. Mannington Commercial Heat Weld Rod is color coordinated for use with Primus and Vivendi. Contrasting colors may be used if so desired. 8

11 Chemical seam sealing heterogeneous flooring Seams may be sealed using the chemical seam sealing method. The seams will be sealed with MLG-33 and the VST 96 professional applicator tip. Before sealing the seams, make certain all seams are clean, dry and free of adhesive contamination. Fill the VST-96 applicator bottle at least 2/3 full of sealer. Tightly screw on the applicator tip. Before using, check the flow through the applicator on a scrap piece of flooring. Insert the fin into the seam cut and lightly squeeze the bottle to apply a uniform bead of sealer approximately 1/8 wide, centered on the seam cut. It is crucial that the seam sealer penetrates the full thickness of the seam cut to insure a proper chemical bond. Do not wipe the sealer from the surface of the flooring. Flash coving All Mannington Commercial sheet flooring can be integrally self or flash coved at the wall line. Flash coving is the procedure in which the flooring material is continued up the wall to the height of 4 or 6 inches. This coving technique eliminates the floor-wall juncture and provides for easy maintenance. When flash coving is required, follow these recommendations: Prepare the area by installing a cove fillet strip and a cove cap (either aluminum or vinyl). The cap should be firmly attached to the wall at the designated height. Outside corners in the cap should be notched and formed rather than mitered. This eliminates a sharp edge at the corner. Cove fillet strip is available in both plastic and wood. The fillet strip should have a minimum 1 1/8 radius. The cove stick should be precisely mitered at all inside and outside corners and firmly secured into the floor or the wall. Best results can be obtained by pattern or template scribing Mannington Commercial Sheet flooring when flash coving is required. Traditional pattern scribing techniques should be followed. Inside corners should be cut net, with no fullness or gaps. Outside corners must be filled using boot plugs. Preformed metal corner caps may also be used. Finishing the job Cover all exposed edges. Use wood molding or vinyl cove base along all walls, cabinet toekicks, etc. Use transition strips in doorways or where new flooring joins another floor covering. Caulk along tubs, toilet bowls, etc. Do not wash the floor for 48 hours after installation. After 48 hours, damp mop to remove residual surface dirt. Follow appropriate maintenance schedule for heterogeneous flooring products. Cautions and miscellaneous Do not place heavy items on newly installed floor covering for at least 48 hours after completion of the installation. Heavy furniture should be equipped with suitable non-staining, wide-bearing casters. Furniture should be moved onto the newly installed floor using an appliance hand truck over hardboard runways. Floor covering subjected to excessive heat and light exposure is subject to thermal degradation. Use appropriate precautions to minimize potential affects on the floor covering. Oil or petroleum-based products can result in surface staining. Do not track asphalt driveway sealer or automobile oil drips onto the vinyl floor covering. Use non-staining walk-off mats at building entrances to remove excess dirt and grit from foot traffic rubber can discolor vinyl floor covering. 9

12 Luxury vinyl tile General information These instructions cover all fully adhered installations of Mannington Commercial LVT; Nature s Paths and Nature s Paths Select luxury vinyl flooring. Nature s Paths LockSolid utilizes a proprietary locking system that is installed as a floating floor and does not require adhesive. All recommendations are based on the most recent available information. The information on this sheet provides general guidelines. For complete details consult Mannington s Professional Installation Handbook or visit our website at manningtoncommercial.com. All instructions and recommendations must be followed for a satisfactory installation. 1. The floor covering, adhesive, and room temperature must be kept at a minimum temperature of 65 F or warmer for at least 48 hours before, during, and 48 hours after installation. Maximum temperature must not exceed 100º F. 2. Install Mannington Commercial LVT only after the jobsite has been cleaned and cleared of other trade apparatus that may damage a finished tile installation. 3. Always check the cartons to assure the pattern number is correct. To minimize shade variation, mix and install tiles/ planks from several different cartons. 4. All subfloor / underlayment patching must be done with a non-shrinking water resistant Portland cement patching compound such as Mannington MVP Never install Mannington Commercial LVT over residual asphalt-type (cut back) adhesive. It can bleed through the new floor covering 6. Mannington Commercial LVT is to be adhered with Mannington Commercial adhesives; Nature s Paths and Nature s Paths Select shall be adhered with Mannington Commercial V-82, M-Guard V-88 or V-95 Adhesive. Subfloor information Careful and correct preparation of the subfloor is a major part of a satisfactory resilient floor covering installation. Roughness or unevenness of the subfloor will telegraph through the new floor covering, resulting in an unsightly surface and excessive wear on high spots. Proper subfloor preparation and suitable underlayment installation are essential for a trouble-free job. A. Wood subfloors 1. GENERAL All wood floors must be suspended at least 18 above the ground. Adequate cross-ventilation must be provided and the ground surface of a crawl space must be covered with a suitable vapor barrier. Wood subfloors directly on concrete or installed over sleeper construction are not satisfactory for the installation of Mannington Resilient flooring products. Wood subfloors must be covered with a minimum ¼ or heavier underlayment rated panel to assure a successful finished flooring installation. 2. UNDERLAYMENT Many times wood panel subfloors are damaged during the construction process or are not of underlayment grade. These panels must be covered with an approved underlayment. Underlayment panels are intended to be used to provide a smooth surface on which to adhere the finished floor covering. It must be understood that underlayment panels cannot correct structural deficiencies. Particleboard, chipboard, construction grade plywood, any hardboard and flakeboard are not recommended as underlayment for fully adhered installations. All have inadequate uniformity, poor dimensional stability, and variable surface porosity. Mannington Resilient Floors will not accept responsibility for adhered installation over these subfloors. Nature s Paths LockSolid can be installed over all wood and wood composition panels provided that they are smooth, flat, structurally sound and free of deflection. This includes plywood, particleboard, oriented strand board (OSB), flakeboard and wafer board. If the surface of the subfloor is not smooth, a ¼ underlayment should be installed over the subfloor. In all cases, the underlayment manufacturer or underlayment installer is responsible for all underlayment warranties. 3. UNDERLAYMENT REQUIREMENTS Panels intended to be used as underlayment should be specifically designed for this purpose. These panels should have a minimum thickness of ¼. Any panels selected as an underlayment must meet the following criteria: Be dimensionally stable 10

13 Have a smooth, fully sanded face so the graining or texturing will not show through Be resistant to both static and impact indentation Be free of any surface components that may cause staining such as plastic fillers, marking inks, sealers, etc. Be of uniform density, porosity and thickness Have a written warranty for suitability and performance from the panel manufacturer or have a history of proven performance Any unevenness at joints between panels must be sanded to a level surface. Gaps between panels, hammer indentations, and all other surface irregularities must be patched with Mannington 2023 or equivalent. B. Concrete subfloors 1. Concrete subfloors must be dry, smooth, and free from dust, solvent, paint, wax, grease, oil, asphalt sealing compounds and other extraneous materials. The surface must be hard and dense, and free from powder or flaking. 2. New concrete slabs must be thoroughly dry and completely cured (at least six weeks). Curing agents, surface hardeners and other additives may cause adhesive bonding failure. These should be removed by sanding or grinding. 3. All concrete slabs must be checked for moisture before installing material. Details for moisture testing can be found in the Mannington Professional Installation Handbook. Anhydrous Calcium Chloride tests conducted according to ASTM F 1869 and/or In Situ Relative humidity tests as conducted according to ASTM F 2170 are the most commonly accepted test procedures. Mannington Commercial V-82 adhesive shall be used for installation of Mannington Commercial LVT on porous substrates including concrete that is dry per ASTM F lbs maximum MVER or ASTM F % maximum relative humidity. Mannington M-Guard V-88 adhesive is recommended for higher moisture tolerance of 8 lbs maximum MVER or 90% relative humidity. M-Guard adhesive will not correct pre-existing moisture problems in older concrete subfloors. Mannington Commercial V-95 adhesive shall be used for non-porous substrates or under hospital beds, heavy rolling loads or where high performance is needed. It is recommended not to install Nature s Paths LockSolid over concrete slabs with a history of excessive moisture or hydrostatic conditions. Concrete subfloors that exceed 8 lbs MVER as determined with the Calcium Chloride test (ASTM F-1869) or 95% RH as determined by the Relative Humidity test (ASTM F-2170) should be considered excessive with regards to moisture emissions. Excessive moisture vapor emissions may contribute to an unhealthy indoor environment. Mannington will not assume responsibility for floor covering failure due to hydrostatic pressure or moisture vapor emission. The final responsibility for determining if the concrete is dry enough for installation of the flooring lies with the floor covering installer 4. Holes, grooves, expansion joints and other depressions must be filled with Mannington 2023 patching and leveling compound (or equivalent), and trowelled smooth and feathered even with the surrounding surface. 5. Concrete floors with a radiant heating system are satisfactory, provided the temperature of the concrete floor does not exceed 90 F at any point. Before installing the flooring, the heating system should be turned on to eliminate residual moisture. C. Existing resilient floor coverings To achieve maximum product performance, fully adhered Mannington Commercial LVT should not be installed over existing resilient floor coverings. In the rare cases where removal of the existing resilient floor covering is not an option, the existing flooring must be covered with MANNINGTON MVP 2023 used as an Embossing Leveler or other appropriate porous underlayment. Note: Consult Mannington s Professional Installation Handbook or the Recommended Work Practices brochure from the Resilient Floor Covering Institute for specific instructions on removal of old resilient floor covering. See RFCI website at RFCI.com WARNING: Do not sand, dry scrape, bead blast or mechanically pulverize existing resilient flooring, backing or lining felt. These products may contain asbestos fibers that are not readily identifiable. Using the above nonrecommended procedures on asbestos-containing material can create asbestos dust. The inhalation of asbestos dust may cause asbestos or other serious bodily harm. Smoking greatly increases the risk of serious bodily harm. 11

14 Nature s Paths LockSolid can be installed over most existing hard surface floor coverings provided that the existing floor surface is well bonded and can be made smooth. Ceramic tile should be made smooth by applying a cementious overlay such as patching or leveling compound. When the removal of the existing resilient floor covering is not an option, the existing flooring must be covered with MANNINGTON MVP-2023 used as an Embossing Leveler or equivalent. Existing vinyl floors should not be heavily cushioned and consist of one layer only. Installation A. Nature s Paths Select Tile As with all tile formats, tiles should be balanced in the work area. Tiles may be laid squarely in the work area or laid out diagonally in the work area. In either case, the room must be accurately measured to square off the area and to determine the center point of the area. The work area should be divided into quadrants designated by striking chalk lines. It is critical that the intersection of the chalk lines be square at 90º. All border tiles should be of nearly equal dimensions and at least one-half of a tile wide. Careful and precise measurements must be taken during tile layout. Adjust this established line to accommodate a balanced layout and then transpose this line to a comfortable width away from the starting wall (approximately 2 to 3 wide). Apply the adhesive in this area and begin installing the tiles. Lay all tiles in the same direction, all directional arrows pointing in the same direction. B. Nature s Paths and Nature s Path Select Plank layout It is also important to balance the layout of the plank format. Proper planning and layout will prevent narrow plank widths at wall junctures. Determine layout to prevent having less than ½ plank width or very short length pieces. As with all plank products, lay the long dimension of the plank parallel to the long dimension of the work area. Accurately measure the room to determine the center line, adjust this established line to accommodate a balanced layout and then transpose this line to a comfortable width away from the starting wall (approximately 2 to 3 wide). Apply the adhesive in this area and begin installing planks. C. Combinations Nature s Paths Select Tile & Plank layout The modularity of Mannington Commercial Nature s Paths Select allows for interesting and decorative combinations of tile and planks. When determining proper layout for this custom installation it is important to consider the dimensions of the modular design unit and then balance the design unit in the work area. Careful and precise measurements must be taken to insure success with a combination design. D. Adhesive application Mannington Commercial V-82, M-Guard V-88, MT- 711 or V-95 adhesive is required for adhering Mannington Commercial LVT except Nature s Paths LockSolid to all approved substrates. Nature s Paths LockSolid utilizes a proprietary locking system that is installed as a floating floor and does not require adhesive. For Nature s Paths and Nature s Paths Select apply the V-82 adhesive with a 1/16 wide, 1/32 deep, 1/32 apart notched trowel. Begin applying adhesive at the pre-determined chalk lines working in two to three foot increments working towards an exit of the room. The V-82 adhesive has a 30 minute working time. Do not apply more adhesive than can be covered in this time. Set Mannington Commercial LVT into the wet adhesive and never work directly on top of the freshly installed product. Roll each installed section of flooring with a threesection 100 pound floor roller. Porous surfaces: Mannington Commercial M-Guard V-88 may be used either wet or as a pressure sensitive adhesive over porous surfaces. To use wet, apply adhesive with the recommended trowel and allow to flash off for 5-10 minutes before installing flooring. Lay tile, plank or sheet goods into wet adhesive according to instructions. Adhesive must transfer to floor product to ensure proper bond. To use as a pressure sensitive adhesive, allow to dry to a tacky state and then install flooring according to instructions within 3 hours. Non-porous surfaces: tile & plank: Apply with the recommended trowel, allow to dry completely from yellow to tan, and lay in the tile or plank according to instructions within 3 hours. The highly aggressive pressure sensitive grip prevents slippage and minimizes seam gaps. Drying time is minutes and will vary depending on temperature and humidity. Installation over areas of incomplete drying can result in job failure. 12
